WATER -CLOiSET FLUSH-VALVE.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed December 3,1906. Serial No. 346,178.

To all whom, it may concern.-

Be it known that 1, JOHN KELLY, a citizen of the United. States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Water-Closet Flush-Valves, ofwhich the following is a specification.

My invention relates to an improvement in the class ofautomatically-opcrating water,- closet flush-valvesfor controlling thesupply of flushing-water to a tank, into which the charge thereof isadmitted by depressing the closet-seat to move the valve to one positionand from which the charge enters the bowl to flush it as the result ofremovin the pressure from the seat to permit the va ve to assume itsother position.

The obgect of my invention 1s to provide a novei construction of valvedevice in the class referred to'which shall render it simple andrelatively cheap to manufacture and durable and reliable in operationand which.

shall adapt the valve proper to be readily accessible for the purpose ofwithdrawingit from its casing for rcpacking and for replacing it intooperative position therein.

Referring to the accompanying drawings, Figure 1. is a broken sectiontaken at the line 1 on Fig. 4 and viewed in the direction of the arrow,showing my improved valve device interposed between a bowl to be flushedand a tank for receiving the charge of flushing-water, the valve properbeing shown in its norrnal position; Fig.2, a view showing the valvedevice in sectional elevation with the valve proper in the osition towhich it is raised W de ressin t e seat to admit a char e ofiiushi11g-water into the tank; Fig. 3, abroken section of thevalvedevice, taken at the line 3 on Fig. 1 and viewed in the direction of thearrow; and Fig. 4 abroken plan view of the rear portion of a closet bowland seat, show-- ing in cross-section the stem of the valve device inposition to be. operated by the seat.

The valve-casing 5 is of general cylindrical sha e and has extendinglaterally from it a holow arm 6, divided longitudinally by a centralpartition 7 into passages 8 and 9, the

arm terminating at its outer end in an 11 turned intcrnally-threadednipple 10 and t e passage 9 terminating at its outer end in a'downwardly-extending internally-threaded nipple 11. As the constructionis represented the partition function of the part? termithlnibe flush'rimfil of a water-closet bow -32 of" nates at the'nipple 11, beyondwhich it is extended to-form the base of the passage 8 and develops intothe nipple 10. Adjacent to the inner ends of the passages 8 and 9 thecasing 5 is shown to be enlarged at 12 and 13 to form chambers, betweenwhich at l ifits one of the two valves, as and for the purpose here.-inafter described. In the lower part of the casing is formed a partition15, containing a central guide-opening 16, and beyond which extends theinternally-threaded nipple 17 for receiving an annular screw-plug 18,between which and the partition packing 19 is'interposed. The upper endof the casing is closed by a screw-cap 20, which is readily'rernow ableto permit access to the valves in the casing, hereinafter described, forfacilitating their withdrawal therefrom, as for repacking them and theirreplacement. -.A nipple 21 extends laterally from the upper part of thecasing 5 about a plurality of inlet-openings 22 therein and is adaptedto be connected by a pipe 23 with a suitable source (not shown) of waterunder pressure. On a stem 24:, which extends at its lower end beyond thecasing, passing, guidingly throu h the partition 15 and stufiing-box'affords bythe plug 18, are provided at suitable distanceapart the valve25, surrounded by packing 26 to closely fit the interior of the casingat 14 above the chamber 13, and the upper valve 27, packed with anupwardly extending cup ed gasket 28, closely fitting theinterior of t ecasing above the chamber 12. The cap 20 serves to confine the valve-stemin the casing.

In the operative position of the valve device it is coupled at thenipple 10 with a closed tank 29, at the nipple 21 with the sup- 1 ply-pie 23, and at the nip le 11 witha 30, leading upwar throu h the usual orany suitable variety. On the bowl is hinged, asrepresented or in anyother suitable manner, the seat '33, from the center of the hinge ofwhich a finger 34 rojectsbackward underneath the lower end of thevalvestem 24-to rise with depression of the seat and affordin the mediumby its depression throu h whidli to raise the seat.

- In g. 1 the movable parts of the valve device and the seat are shownin their normal relative positions, to which they are brought by.the'watcrpressure, as hereinafter ICC scribed. By de' ressing the seat33 the re sultant rise of t 'e stem 2% brings the valve 7 25 into theannular space at 14 to close cum 'munication between the passages 8. and9 and the valve 27 above the inlet-openings 22 to open communicationbetween the pipe 23 and the assage 8 to the flow of water "from the suppy into the tank 29. While the seat {113111911115 depressed this supplycontinues to.

fill the closed tank to the extent that its air bound condition willpermit. When the lowering pressure upon the seat is released,

thewater-pressure from the supply against the valve 27 and that exertedby the compressed air in the tank through the passage 8 against thevalve forces downward the valve-stem against the finger 34 to raise theseat into the osition from which it is ready to be again epressed foreffecting introduction into the tank of the next charge offlushingwvater,

. and the charge in the tank 29 flows through the passa e 8past thevalve 25 into the passage 9. an thence into the rim 31 to exert itsflushin purpose, this flow continuing until the tan is em tied and incondition to re ceive the nextc large as the result of depressing 'the'seat to close communication between the two assages 8 and 9 and opentending hollowarm adapted to be coupled with a flush-tank and containinga partition dividing it into passages open to said casing, one of saidpassa es being adapted ,tobe coupled to the fins -ri m-of a closet-bowl,an inlet leading into the upper part of the casing and adapted to beconnected with a source of water-supply, a valve-stem reciprocablyconfined in the casing to extend at one end beyond the same and providedwith a valve normally closing communication between said inlet and oneof said passages for supplying the tank, and with a second valve normally opening communication between said passages, for the purpose setforth.
